I report to the county that I live in, every 90 days, to update answers for a list of pre-set questions, such as address, phone number, automobiles, email address, employer, etc. Then I sign it stating that it's true. Within the next 90 days, I will be visited by city police and county police, with copies of my answers to those questions, informing me that they are only trying to verify my answers. I want to know what is the requirement, in law, that I am to answer the questions that I have already answered at the 90 day report? What are the requirements of me answering questions that aren't on the list such as, is my cell phone a smart phone, how many computers do I own, can they come in and look at them, do I have a passport, can they see it, do I do this or that and on and on? I realize that the average citizen doesn't have to answer those questions, but everybody knows that the ones of us who have committed the unforgiveable crime don't deserve anything, so please spare me all the usual answers of all the different ways I should burn in hell for a crime I committed 32 yrs ago. I really would like to know if the police can, under the threat of arrest, force me to answer questions that are not required in writing, by law. Do the police have the right to stand there, on my porch, with one hand on the butt of their pistol, in front of my wife, children, and neighbors, demand that I answer their questions? Do I even have to answer my door? One other question is, since the Mo. State Police mail me a letter, telling me what my requirements are concerning that letter, am I required by law to do it? Am I even required by law to open my mailbox, take out a letter, and then do everything the letter says to do, just because it's from the police?
